Question 22

Sodium carbonate reacts with excess dilute hydrochloric acid according to the equation:

Na2CO3+2HCl→2NaCl+H2O+CO2\text{Na}_2\text{CO}_3 + 2\text{HCl} \rightarrow 2\text{NaCl} + \text{H}_2\text{O} + \text{CO}_2Na2​CO3​+2HCl→2NaCl+H2​O+CO2​

The relative formula mass of Na2CO3\text{Na}_2\text{CO}_3Na2​CO3​ is 106. At room temperature and pressure, one mole of any gas occupies 24 dm3.

Calculate the volume of carbon dioxide produced when 5.30 g of sodium carbonate reacts with excess dilute hydrochloric acid.
